PRIME hand injury diagnosis system takes hold of innovation prize

by Vladislav Savov posted Jul 8th 2009 at 11:12PM

It may look like little more than a pegboard and a force meter at present, but the PRIME hand-strength measuring device has already won first place at the IShow innovation showcase. Its magic lies in the custom software loaded onto the appended PDA, which makes it possible to accurately and repeatably diagnose hand and wrist injuries that doctors currently test for by squeezing and prodding. The Rice University students responsible for the Peg Restrained Intrinsic Muscle Evaluator have applied for a patent and are planning to commercialize the device, so we'll be looking for it on the next episode of House.

Probabilistic logic makes microchip more energy efficient

by Darren Murph posted Feb 9th 2009 at 6:09AM

We'll be straight up with you -- there's a lot of fancy work going on with this one that laypeople will have a tough time grasping, but the long and short of it is this: a team from Rice University (Krishna Palem pictured) and Nanyang Technological University have created a microchip that "uses 30 times less electricity while running seven times faster than today's best technology." Already crying snake oil? Not so fast. By trashing the traditional set of mathematical rules (that'd be Boolean logic) and instead applying probabilistic logic, researchers have figured out how to deliver similar results with a fraction of the energy. The tech is being dubbed PCMOS (probabilistic CMOS), and could eventually end up in embedded systems and even cellphones. In the case of the latter, this type of chip will be able to display streaming video on a minuscule display with more artifacts than usual, but due to the small screen size and the human brain's ability to piece together nearly-perfect images, the errors involved would be all but forgotten. Meanwhile, your battery bar would still be nearly full. We always heard there was beauty in imperfections -- now, at long last, we finally get it.

Rice University rolls out new and improved "nanocar"

by Donald Melanson posted Feb 4th 2009 at 4:11PM

Nano-sized letters are one thing, but nothing impresses the nanotechnology community like creepy crawly nanotech, and some researchers from Rice University look to have fully delivered on that point with their latest so-called "nanocar." At about two nanometers in length, the new nanocar apparently doesn't represent a drastic reduction in size over the previous incarnation, but it does have the notable advantage of being able to "travel" across surfaces at room temperature (a temperature of 200° Celsius was required before). Interestingly, that breakthrough was actually discovered by accident, and was later able to be confirmed using a mix of time-lapse photography and a new tracking algorithm. As you might have guessed, however, they're still quite a ways away from being able to actually control the car, although the researchers say using six wheels instead of four could help with that, as could tracks to keep 'em going in one direction.

Rice University turns skeleton into a data network

by Thomas Ricker posted Jun 14th 2007 at 11:36PM

We've seen plenty of ideas and even a patent related to the employment of human skin in the transport of data. We've also seen our fair share of bone conducting audio products come to market in the last few years. Now in a synthesis of the two, scientists at Rice University have developed a technique whereby rattles to the skeleton can transmit information to gadgets and medical devices strapped on (or inside of) your meat sack. Their approach has resulted in "amazingly few errors" even when using low-powered vibrations. Great, soon our handshakes will transfer both biological and software-related viruses? Oh boy.

Rice University scientists create a revolutionary single pixel camera

by Cyrus Farivar posted Oct 3rd 2006 at 3:40AM

While most folks get real excited over a cam like the Seitz 6x17 Digital that shoots at 160 megapixels, Rice University researchers have decided that less is, in fact, more. Scientists at the esteemed academic ivory tower in Houston, Texas have determined a way to build a single pixel camera that they claim will be cheaper way to take pictures in the future. Using one photodiode and one digital micromirror device (DMD) -- which is used primarily in digital TVs and projectors to convert digital information to light (and vice versa) via its thousands of tiny mirrors -- light is "shined onto the DMD and bounced from there though a second lens that focuses the light reflected by the DMD onto a single photodiode." Then, the DMD's mirrors shuffle at random for each new light sample, creating a new pixel value. The pair of lenses and the DMD thus compress data from a bigger image (left) into a smaller approximation (right). That said, don't expect this technology to make your consumer digicam any cheaper real soon, as the prototype requires five minutes for the engineers to take a picture using this technique, and even then, they can only shoot still objects.

Nanomagnetic vortices could lead to bigger hard drives, faster RAM

by Cyrus Farivar posted Sep 8th 2006 at 4:30PM

You know, we were sitting in our editors' meeting the other day, and we all came to a very serious consensus about our reportage these days. There's been a serious dearth of vortices in our articles, and so we're going to do our darndest to bring you more coverage of these truly awesome swirling clouds. Fortunately for us, those egghead physicists down at Rice University know how to read our minds. A team over in Houston used a scanning ion microscope to create and measure "ultra-thin circular disks of soft magnetic cobalt" ranging in diameter from one micron to 38 microns. According to a press release issued by the university, the six micron wide (about the size of a red blood cell) magnetic vortex is "a cone-like structure that's created in the magnetic field at the disk when all the magnetic moments of the atoms in the disk align into uniform concentric circles." (Whatever that means.) Lead researcher Carl Rau, professor of physics and astronomy at Rice University, said that this new advance may lead to storage densities "in the range of terabits per square inch," and went on to say that "magnetic processors" and "high-speed magnetic RAM" may also be in the works. Now that we think about it, this is probably what would happen to the offspring of Storm and Magneto too.
